PAPER-BOX-MAKING MACHINE.

Specification of Letters Patent.

Patent-ed May 5, 1914.

To all whom it may concern:

Be it known that we, FRANK N. WEIS and WILLIAM C. WEIS, citizens of theUnited States, residing at Monroe, in the county of Monroe and State ofMichigan, have invented certain new and useful Improvements inPaper-Box-Making Machines; and

vwe do declare the following to be a full,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis-specification.

Our invention relates to and its object is to provide a machine forpressing and holding together the glued meeting surfaces of theoverlapping flaps of a paper-box-blank.

Our invention is also designed to provide means for cutting a holethrough the flaps while thus held in place to form a mouth for thecompleted box.

Our invention furtherrelates to certain details of constructionhereinafter described, and which will be pointed out in the claims.

lVe attain the objects above indicated by means of the devices,construction and arrangement of parts hereinafter described, and shownand illustrated in the accompanying drawings, in which,--

Figure 1 is a side-view of our device, for the most part in centralvertical sectional elevation; Fig. 2, a top-plan view of our machinetaken on line w-w Fig. 1, the upper ring hereinafter referred to beingremoved; Fig. 3, a top-plan view of our machine with the upper rin inplace but partly broken away to show t e second ring hereinafterreferred to, which ring is also partly broken away to show the top ofthe formers and cutting-dies hereinafter re ferred to; Fig. 4, afront-elevation, on an enlarged scale, of the lower and middle ringhereinafter referred to with the housing for the former, and the slidefor the presserblock and cutting die, hereinafter referred to, in placethereon; Fig. 5, a top-plan view, in section on line g -y Fig. 6,showing the guide for the sliding presser-block hereinafter referred to;Flg. 6, a front-elevation of the same; Fig. 7, a front-elevation of thesame on an enlarged scale with portions broken-away to show the internalconstruction and arrangement of the cutting-die,

a side-elevation of the upper and lower rings of our machine, disclosingthe devices for tilting the former-block to permit the application andremoval of the blank to be operated upon, together with the device foractuating the slide which carries -and actuates the resser-block andpunch.

Like numerals of reference indicate like parts throughout the drawings.

In the drawings, 1 is a pedestal in the vertical bore of which issocketcd a shaft 2 held rigidly against rotation by a set-screw 3. Atthe top of the shaft is rigidly secured a horizontal ring 4. Journaledupon the shaft 2, just above the pedestal, is a ring 5 which supportsand carries a ring 6, also journaled on the shaft 2 and intermediate thetop ring 4 and the ring 5. The connections between the rings 5 and 6 bywhich they are held rigidly in fixed relation consist of rods or bolts7, (see Fig. 4) threaded and provided with nuts at their lower and upperends, as shown. The rings 5 and 6 are caused to revolve upon the shaft2by means of the beveled gears 8 connected by suitable intermediategearing with the driving pulley 9. -A clutch 10, actuated by foot lever11, throws the gears into and out of operative connection with thedriving pulley so that the rotation of the rings 56 is quickly startedand stopped as may be de-' slightly conical, the cone being truncated bya round hole cut or punched therethrough.

12 is a former-block of the exact sizeand shape of the interior of thebox, except that it is longer, the upper end of the former be- I ingslightly conical, as indicated in dotted lines in l igr-l and as shownin Fig. 7. In the present machine there are, forillustration, six ofthese blocks and a description of one, its supports and its mode ofoperation will answer for all. The block is hollow and has a hole 13 inthe center of its top which leads down into thehollow of the block. i Ltthe bottom of the cavity of the block is an outwardly inclined opening 1for the discharge of punchings, as hereinafter explained. Secured to thetop of the ring 5 cqui-distant intervals, between the posts 7, areblocks, each having a pair of upright lugs 15 between which the blocks12 are, at their lower ends, pivotally supported, as at 16, the pivotspermitting the blocks to swing outwardly, as indicated in the dottedlines in Fig. 1, or into upright position.

" The block 12 at its lower end has an arm 17 which projects inwardlytoward the central upright shaft, upon which arm is journaled a roller18. At the front of the machine,- that is, the partnearest the operator,and supported by a collar 19 on the shaft 2, is a pair of shortsegmental tracks 19 (see Fig. 9) lying in the path of the roller 18 andbetween which the roller must travel in its circuit. These tracks 19 areinclined upwardly from the approach side to their middle and from thencedownwardly to their opposite ends so that when the roller travelsbetween these two tracks it moves upwardly and then downwardly, causingthe former-block 12 to first tilt outwardly upon its pivot and theninwardly into upright position.

iilounted upon the ring 6, in vertical alincment with the former blocks12, is a series of presser-blocks 20, a description of one of which willsufiice for all. The presser-block is provided with wings orf elongatedlugs 21 which slide vertically in guides or ways 22, secured to theouter rim ot the ring 6. (See Fig. 4.) The bottom of the presser-blockis concaved to conform to the conical upper end of the former-block 12.tally into two parts 2020",the two parts being held asunder by stillspiral springs 23 which are held in position by sockets 24: in theopposed faces of the parts 2Q20 The upper block-part 20 is rigidly orintegrally connected with the wings or slides 21. The lower block-part20 is slidably connected with the upper part by means of plate 20rigidly bolted at its lower end to the part 20 and having a verticalslot 2O near its upper end through which slot a set-screw 2O enters thepart 20, the arrangement being such that the part 20 has a limited movement toward and away from the upper part 20*. The twopresser-bloek-parts are furthermore held in alinernent and slidabletoward and away from each other by means of a cutting punch or plungerrigidly con- The pressenblock is divided horizon-' nected at. its upperend with the part 20 and movable in the vertical axis of part 20, ashereinafter explained. Upon the top of the block-part 20 are twoupwardly'projecting lugs 25 between which is journaled a roller 26. T heshaft of this roller also carries another roller 27. The underside ofthe top ring 1 forms a track against and upon which the roller travels.part of the machine this ring is broken away, as illustrated in Fig. 3.Secured to the underside of the ring 4: at the front of the machine andcoinciding with the interrupted portion of the ring is a short segmentaltrack 28 which lies in the path of the roller 27. This track is bentupwardly at its approach end and then runs horizontally and at itsopposite end is inclined downwardly, as clearly shown in Fig. 9, thearrangement being such that when theroller 26 rides against itsoverhanging trackthe presser-blocks are pushed downwardly, and when theroller 26 reaches the open space in the front of the ring 1 the roller27 mounts and rides upon the short track 28, thus lifting thepresserbloclrs and holding them elevated during a short portion of theircircuit.

The two blocks 2O --20 are bored axially and vertically -for thereception of a punch 29. The upper end of the punch rests against theupper end of the socket in the part 20*, and is there held by itsengagement with the inner end of the set-screw 20*. It will be seen thatif the block-part 20 be held stationary and it the upper block-part 20be depressed, the plunger will be moved down wardly with its lower endprojecting beyond the bottom of the block 20*. In the track of theroller 26, near the end of its circuit, is a downwardly projectingshoulder 30 which depresses and causes the roller 26 to travel in alower plane until it is released by the gap in the front of the ring 4-.i

The operation of our device, thus far described, is as follows: Assumingthat the parts are assembled in operative relation, as

blocks tilted outwardly, as shown in dotted.

lines in Fig. 1. Next the open end of the unfinished box is slipped downover the former-block and the end fiaps,which have been previouslycoated with glue or other suitable adhesive,-are folded inwardly tooverlap each other in proper relation. A touch upon the clutch-pedalstarts the machine, and the roller 18, traveling down the inclined guide19, swings the former-block into upright position. At the same momentthe roller 26 asses under the end of its overhanging trac and forces thetwo .pressenblocks 20*20 downwardly so that the underside of the block20 rests with At the :t'ront a heavy pressure on top of the foldedflaps. The flaps are held thus pressed together until the roller 26reaches the shoulder 30 where the roller and the upper block are forcedfarther downwardly, thus,.through the springs 23,pressing the lowerblock 20 down with a strong pressure on top of the box-flaps, and at thesame time forcing the punch 29 through the flaps of the box, leaving asmooth round hole. The punchings are discharged through the opening 14.The roller 26 now emerges from be neath its track and at the same timethe roller 27 mounts its upwardly inclined track 28 and lifts theresser-blocks away from the top of the former-block. The next in-' stantthe roller 18 strikes the upwardly inclined track 19, tilting theformer; block forwardly to permit the removal of the box and thesubstitution of another. As the former-blocks successively tilt towardthe operator he removes his foot from the clutch pedal, causing a pausein the procession of boxes under pressure, thus prolonging the operationand giving time for the adhesive to set, and giving time to remove andsupply boxes. The lifting of the resser-blocks tends to slip, the boxup. wardly upon the former block. The tilting of the former-blockforwardly with the top of the box held fast would now break and ruin thebox. To overcome this diffieulty we provide the device, illustrated inFigs. 3 and 8, which show a top-plan view and a front elevation of thedevice. 31 is a bracket secured to and projecting horizontally from thering 4 and carrying a downwardly extending rod 32 upon the lower end ofwhich is journaled a horizontal arm 33 which is held normally pressedinwardly by a coiled spring 34 engaged with the rod and armrespectively. At the outer end c the arm 33 is journaled a roller 35shod,-preferably, with india rubber. The spring 34: causes the roller topress against and ride upon the front sides of the boxes in successionat the instant the presser-blocks are lifted, thus holding the boxes inplace upon their blocks so that they cannot be lifted away by the upwardmovement of the presser-blocks.

Having described our invention, what we claim and desire to secure byLetters Patcut, is, f

1. In a device of the described character, a rotary frame; a series ofhollow forms mounted upon said frame, each having leading into thecavity of the forman aperture the margin of which forms one of themembers of a cutting die, and having a mouth for the discharge ofcuttings; a corresponding series of resser-blocks co-acting with saidforms; a corresponding series of punches carried by the presser-blocksand. in cooperative relation to said apertures in the forms; means forholding the blocks pressed toward the forms during a part of theirrotation, means for moving the presserblocks away from the forms duringthe remainder of their rotation; means for actuating the punches, andmeans for imparting an intermittent rotary movement to the frame.

2. In a device of the described character,

a rotary frame; a series of forms mounted; 1

of their rotation; means for projecting the punches during the formerpart of the rotation of the presser-blocks; means for retracting thepunches during the latter part of the rotation of the presser-blocks,and means for imparting an intermittent rotary movement to the frame.

3. In a device of the described character, a rotary frame, a formcarried by the frame, a presser-block co-acting with said form andcomprising two parts held normally in separated relation by suitablesprings, a punch carried by one of said block-parts and adapted toproject through the other of said block-parts, combined with means formoving the presser-block into pressing relation with the form duringpart of the r0- tation of the frame, means for increasing the pressureof the presser-block during such part of its rotation, the arrangementbeing such that such increased pressure projects the punch into theform.

4. In a device of the described character, a rotary frame, a formmounted thereon, a presser-block arranged to co-act with said form,means for pressing the block toward the form during part ofthe rotationof the frame, means for retracting the presserblock during the remainderof the rotation of the frame, combined with a spring controlled roller35 disposed in the path of the side of the form and in advance of thepoint of retraction of the block.
